Anti-electromagnetic interference monolithic capacitor

The utility model relates to the technical field of capacitors, in particular to an anti-electromagnetic interference monolithic capacitor, which comprises a metal shell and a capacitor body, the metal shell is of a hollow structure with an opening at one end, and the capacitor body is embedded into the metal shell through the opening at one end of the metal shell. The guide part comprises two guide plates which are symmetrically arranged on the inner side of the opening of the shell, the guide plates are connected with the shell through air springs, rolling shafts are arranged on the opposite sides of the two guide plates, and the rolling shafts abut against the side edge of the capacitor body under the elastic force of the air springs. According to the utility model, the rolling shafts are arranged on the guide plates, and when the capacitor body is arranged in the metal shell, the rolling shafts on one sides of the guide plates can convert sliding friction between the guide plates and the capacitor body in
